Source
Microsoft Power Automate: What's the difference between Premium and Process plans?

Premium ($15/user/month) provides attended automation with cloud flows and standard RPA. Process plan ($150/bot/month) enables unattended automation where bots run without human intervention on virtual machines for high-volume, repetitive tasks.

Source
Microsoft Power Automate: Does Power Automate support long-running workflows?

No. Power Automate is not suitable for long-lasting workflows because they can run without warning and fail unexpectedly. The platform is built for linear, branching logic (if-then) rather than complex, multi-step business processes involving multiple stakeholders.
